[SEL] Curved spokes ...engine rotation

[Jim and Diane]

Do the bolts automatically change color when they cross the equator.  Are 
they legal in OZ.
How much do you charge?  What size do I need?

As an optional accessory item to bilateral obverse thread
systems, we are making available special color-coded bolts
to help the engine builder keep track of which is which.
Since left hand bolts look just like ordinary bolts, we
offer special bright red bolts to fit the right-hand
threaded spokes still used on the right side of the wheel.
This prevents them from becoming confused with the left-hand
threaded bolts.
